I'll be placing my chassis order soon, but am a little stressed with regards to the IRS...
My donor bug is a UK import '68.
The online store lists parts for many different lengths of IRS
I'm really confused...how do I know which is the one I have?
Thanks, N.
"Understeer is when you hit the wall with the front of the car, and oversteer, the rear. Hp is how fast you hit the wall, and Torque is how far you take the wall with you."
IRS different lengths on a beetle, never heard of that ???, there are two different lengths of swing axles, yes, early up to 65/66 and later as all our 67 and later have. All IRS beetles are the same.
For what it's worth, ignorance has no limits ......
As an example, I have posted part of a results-returned page from a search on the online store.
Note the variety of options available...

[quote=Armand]The length every body refers to is the length of the torsion bar itself
VW used at least 3 different types of torsion bar (lengths over the
years)
The ovals had a long torsion bar which protruded through the torsion
cover.
Later bugs (all SA models had a shorter torsion bar completely covered
by the torsion cover.) there are also several different thicknesses of
torsion bar.
The type three models all used the long torsion bars.
When IRS came out VW used long torsion bars with this setup. Probably in
order to stabilize the suspension attachment
The type 3 being heavier than the type 1 had a double spring blade and
slightly different hole spacing on the swing arm nothing major.
The type three and type 1 had the same gearbox sideshafts (equal length)
cv's etc.
The automatic type three had different length side shafts on the left
and right due to the automatic gearbox being off center.
When you talk aftermarket then it is a new ball game
Because it is advantageous to have a wider track on an off road vehicle
lots of combinations can be had. Use a modified swing axle spring plate
(closed torsion bar cover) with a long torsion bar and you space the
suspension out by 75 mm (3")this requires custom axles and swing arms
If you use long std. IRS spring plates with short torsion bars then it
is possible to narrow the rear track by 3 inches This being done for
drag cars and wider wheels (significantly)
Using pairs of the long and short auto axles other combinations are
available[/quote]
